Great work Luke, thanks for posting this. Very small note: P5 of the Venturi Effect goes more to the left, and joins PV rather quickly.

Also, the ledge marked "the Terrace" is also known as "the Bivy Ledge". To make things more confusing, I have also heard of the big ledge atop P2 of P.V. (also shared with Venturi, Sunspot, etc) called the Terrace. I don't know what's correct.
